Plumbing fixture



FIG. 1 is a right, top, front perspective view of a plumbing fixture embodying our new design;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a top plan view thereof;

FIG. 4 is a right side elevational view thereof, the left side elevational view thereof being a mirror image of the right side shown; and,

FIG. 5 is a rear elevational view thereof.

The dash-dash broken lines in the figures are for the purpose of illustrating unclaimed surfaces or environment of the design. The dot-dash-dot broken lines define the unclaimed boundary of the design. The broken lines are thus not part of the claim. 

CLAIM The ornamental design for a plumbing fixture, as shown and described.
